1  Using Arduino / Displays / Re: How to read HD44780 LCD programmatically on: April 26, 2013, 04:59:19 pm
Hello Retroplayer,

do you have finished your code? If so, please publish it here, or mail it to me. I am looking for such a code for my "Textsystem" to write, edit, read text strings to/from a 2 x 16 or 2 x 20 or 4 x 16 or 4 x 20 LCD, and store the text, in case of error edited text, in arduinos- or external eeprom. I create and edit the text strings with a german ps/2 keyboard.

PS/2 keyboard functionality of writing  and editing text, including cursor control for the LCD, are ok so far. Because all displayed charcters are stored within the lcd, the easiest way to store the displayed text in external eeprom ist to read the text from the lcd RAM, and move it to the eeprom. So your code would help me very much.
